If you want your bubble plot to include groups, you can display them overlaid on the same graph.

To create a bubble plot with overlaid groups, you must use a worksheet that contains three columns of measurement data and at least one column of categorical data for grouping. All columns must have the same number of rows.

C1 | C2 | C3 | C4 |
---|---|---|---|

Combined MPG | Total Volume | Retail ($1000) | Safety (0-5) |

19.25 | 187.0 | 31.3 | 4 |

25.50 | 132.3 | 31.0 | 4 |

39.55 | 132.3 | 35.6 | 5 |
